DETAILED DESCRIPTION OF THE INVENTION

[0025] Referring to the drawings and initially to FIGS. 1-3, anexercising device 1 in accordance with a preferred embodiment of thepresent invention comprises a tube 10, two wheel frames 20, a rod 30,and a housing 40.

[0026] The tube 10 has an outer wall provided with two oppositeextension plates 18. Each of the two opposite extension plates 18 has atop face provided with a handle fixing seat 19 for insertion of one oftwo handles 50. Two spaced handle support racks 60 and 61 are secured onthe two opposite extension plates 18 and are located beside the twohandle fixing seats 19 for insertion of the two handles 50 after the twohandles 50 are detached.

[0027] The tube 10 has a bottom face secured with two parallel shafts 17which are vertical to the tube 10. Each of the two parallel shafts 17has two ends each having an outer periphery provided with a catch plate170. A first plug 12 and a second plug 11 are respectively inserted intothe two ends of the tube 10 as shown in FIG. 3. A first handgrip 33 thatmay be rotated freely is pivotally mounted on an outer side of the firstplug 12. The second plug 11 has a center formed with a shaft hole 110.

[0028] Two opposite movable blocks 13 are respectively mounted in thetwo ends of the tube 10, and are respectively rested on the first plug12 and the second plug 11. An elastic member 16 is mounted in the tube10, and is urged between the two opposite movable blocks 13, so that thetwo opposite movable blocks 13 may be respectively urged on the firstplug 12 and the second plug 11. Each of the two opposite movable blocks13 has a first side formed with a receiving chamber 132 directed towardthe first plug 12 and the second plug 11, and has a second side formedwith a through hole 130 which is formed with two radially oppositegrooves 131. The receiving chamber 132 of the first side of each of thetwo opposite movable blocks 13 is formed with two radially oppositelocking grooves 133 each having a cross-section the same as that of thegroove 131 of the through hole 130. The receiving chamber 132 of thefirst side of each of the two opposite movable blocks 13 is fitted witha spring 14 and a mounting ring 15.

[0029] As shown in FIGS. 2 and 3, each of the two wheel frames 20 isprovided with two arcuate support legs 21 each having a first endpivotally mounted on one of the two ends of each of the two shafts 17,and a second end mounted on a wheel axle 22 which has two ends eachprovided with a roller 23. The first end of each of the two arcuatesupport legs 21 of each of the two wheel frames 20 is protruded with astop flange 210 that may be rested on the catch plate 170 of each of thetwo ends of each of the two shafts 17, thereby providing a supportingand positioning effect.

[0030] The rod 30 has a first end extended through the shaft hole 110 ofthe second plug 11 and the through hole 130 of a first one of the twomovable blocks 13, and integrally combined with a locking member 31. Thelocking member 31 has an outer periphery provided with two radiallyopposite lugs 310, so that the locking member 31 has a cross-section thesame as that of the through hole 130 of the movable block 13. The rod 30has a second end provided with a rotation wheel 32 that may drive therod 30 to rotate. A second handgrip 33A that may be rotated freely issecured on the second end of the rod 30.

[0031] The housing 40 includes an upper cover 41 and a lower cover 42combined with each other, so that the tube 10 is enclosed between theupper cover 41 and the lower cover 42 of the housing 40. The lower cover42 of the housing 40 is formed with multiple slits 420 for passage ofthe arcuate support legs 21 of each of the two wheel frames 20. Thelower cover 42 of the housing 40 has a bottom face formed with areceiving recess 421 (see FIG. 3) for receiving and folding the arcuatesupport legs 21 of each of the two wheel frames 20. The bottom face ofthe lower cover 42 of the housing 40 is formed with multiple insertionseats 422 (see FIG. 3) for snapping and positioning the wheel axles 22of each of the two wheel frames 20. The upper cover 41 of the housing 40is formed with two opposite through holes 410 for passage of the twohandles 50. The upper cover 41 of the housing 40 is formed with anopening 411 for placing the handles 50 that are detached and placing anarcuate support plate 70 that may be used to abut a user's abdomen. Aremovable cover 412 is mounted on the upper cover 41 of the housing 40to enclose the opening 411.

[0032] As shown in FIG. 4, when the exercising device 1 in accordancewith a preferred embodiment of the present invention is used, the firstend of the rod 30 may be moved toward the first handgrip 33, so that thelocking member 31 secured on the first end of the rod 30 may passthrough the two grooves 131 of the through hole 130 of a second (left)movable block 13. Then, the rod 30 may be rotated by the rotation wheel32, so that the lugs 310 of the locking member 31 may be inserted intoand locked in the two radially opposite locking grooves 133 of thereceiving chamber 132 of the second movable block 13, so that thelocking member 31 may be urged by the spring 14 in the receiving chamber132 of the second movable block 13. Thus, when the first handgrip 33 andthe second handgrip 33A are pulled outward relative to each other, thesecond (left) movable block 13 may be pulled by the rod 30 to movetoward the first (right) movable block 13, thereby compressing theelastic member 16 in the tube 10, so as to provide a proper elasticresistance, thereby capable of exercising the muscles of the arms andthe chest of the user.

[0033] As shown in FIG. 5, the rod 30 may be pulled by the secondhandgrip 33A to move outward, so that the locking member 31 secured onthe first end of the rod 30 may pass through the two grooves 131 of thethrough hole 130 of the first (right) movable block 13. Then, the rod 30may be rotated by the rotation wheel 32, so that the lugs 310 of thelocking member 31 may be inserted into and locked in the two radiallyopposite locking grooves 133 of the receiving chamber 132 of the first(right) movable block 13, so that the locking member 31 may be urged bythe spring 14 in the receiving chamber 132 of the first (right) movableblock 13. Thus, when the first handgrip 33 and the second handgrip 33Aare pushed inward relative to each other, the second (left) movableblock 13 and the first (right) movable block 13 may be pushed to movetoward each other, thereby compressing the elastic member 16 in the tube10, so as to provide a proper elastic resistance, thereby capable ofexercising the muscles of the arms and the chest of the user.

[0034] As shown in FIG. 6, the two wheel frames 20 may be expanded, sothat the exercising device 1 may be supported by the rollers 23 stably.The user's two hands may hold the two handles 50 to move the exercisingdevice 1 reciprocally so as to bend and stretch the user's bodyreciprocally, thereby exercising the user's body. The handgrip 33A maybe rested on the wall, whereby the elastic member 16 in the tube 10 maybe compressed to produce a restoring force, so as to assist the user topull the exercising device 1 backward, thereby preventing the user'swaist from being injured.

[0035] As shown in FIG. 7, the arcuate support plate 70 may be combinedwith the second handgrip 33A, and may be rested on the user's abdomen.Thus, the user's two hands may hold the two handles 50 to move the tube10 toward the user's abdomen whereby the arcuate support plate 70 may bepushed by the second handgrip 33A to urge the user's abdomen, so thatthe elastic member 16 in the tube 10 may be compressed to produce arestoring force, thereby exercising the muscles of the user's abdomen.

[0036] As shown in FIG. 8, the bottom of the exercising device 1 isprovided with wheel frames 20, so that one side of the exercising device1 is heavier. Thus, the user's two hands may hold the two handles 50 toturn the exercising device 1, whereby the heavier side of the exercisingdevice 1 may produce a centrifugal force, so that the exercising device1 may be rotated continuously, thereby capable of exercising the musclesof the user's arms.

[0037] Although the invention has been explained in relation to itspreferred embodiment as mentioned above, it is to be understood thatmany other possible modifications and variations can be made withoutdeparting from the scope of the present invention.
